1908 I ave shown improved means for forming sheaves into tightly boundelev steel to a wagon arranged therein for transportation to a suit-'Accordin'g to my resent invention, 1 have vided means w ereby ientlyformed into a stack. Heretofore it has been customary to remove from awagon by means of pitch-forks and barn-or on to a stack as its formationprogresses. This is 'a slow and laborious operation and much of thcgrainis I and carried with but litt 40 shocks and then swung over.

I- have provided mechanism whereby the shocks, each consisting of aplurality of sheaves, may be quickly raised from a,wagon to the stackanddroppedwthere le labor for the handsandcolm grain.-

The arrangement issii'ehthat thecrane-arm may be first swungl over a Wagon, andthe hoisting devices tthe'stack to deliver the shocks thereto.

Fi devices for inding toget era layer ofshocks. Fig. 7 is a perspective'view showing how the crane-frame issupported on the track. Fig. ,8 shows a complet d Stack inclosed in acanvas cover.

The woodrails A are made in sections and carry metal track sections B.The rails are supported by posts C having braced bases (1" which maybeattached to the ground by'pins D. The ends of the rails fit in mortisesin the tops of the posts and-are held firmly by pegs or pins d. Therails are held the desired the crane-frame E, mounted on'the sli es E,which are adapted to travel back and forth on the tracks. The slides areprovided with anti-friction rollers f, and the crane-frame comprisesupright parts e and a top part G, preferably made in sections as shownand provided with intervening )lates g, by means of which the sectionsmay e secured tightly andwhereby the'top part may be made wider ornarrower as desired.

The-crane arm H is extensible as to length, being made in two p bolts hwhiclrmayrbe taken out and replaced after the arm'sections have beenadjusted to the desired extent. The cranearm is pivotedto thecrane-frame by a vertical bolt I which extends through thearm section itthrough the upper l'ramc part (1 and the bracesJ and K and the part (iand the part the outer end of the crane-arm there is *eL, by means ofwhich the arm may be desired direction. 0n arm there is also swungaround in any the outer end of the craneilley-block the lower end of theloop of which is protached a bail O carrying at its lower end a clampingband.

The wagon is driven close to thetracks near the crane-frame so that the crane-arm may be swung aroundover the wagoii. The band W is then passed over a shock and by means ofthe screw rod W firmly applied thereto, then by means of the ropes N andL the shock may be hoisted and carried to the proper positionover thestack and placed thereon. j

In order to move the crane-frame back i and forth on the track I providetwo ropes S for pulling the frame in one direction.

These ropes are attached to the slides F and extend over pulleys s onthe front end of the tracks. and ropes T, attached to the slides,

extend through pulleys U at the rear ends of the tracks and then extendforwardlyto the stack so that the attendant may pull the I crane-frameback and forth as desired to cause it to assume the proper positionrelatively-to the Wagon and the stack.

I first form a tier of shocks X over the desired area and then place ontop of this another tier of shocks X" and so on until the desired heightis reached. In order to avoid tramping on the grain I preferably use aplatform board Y, which may be placed .on the tier completely formed,for the attendant to stand on while the next tier is being constructed.

When it is desirable to form a stack on the side of a hill,Ipreferablymake the post 0 adjustable, as indicated in Figs. 2, 3 and 4.

Thetrack is preferably always made level, the ost being'suitably adjustedyertica-lly for t is purpose. 4, the lower part cof the post is attachedto the base C. and in this part is arranged a telescopic verticallyadjustable part c, which is attached to the track.

The loose cap sheaves may 'be taken from the wagon separately and usedin building the stack in any desired Way. Some of u tl fem may be usedto form the top of the stack as indicated at X in Fig. .8.

The stack when completed should be inclosed in a canvas cover X which isheld in place by ropes w secured to pegs 1E driven I claim'as myinvention:
